obj import 90° rotated in twinmotion :) !

[vinsse2001]

Hello all,
I'm new on SH3D, I want to try it to make a 3D view of my future house and after, import it in Twinmotion (3D view is interesting with garden, trees...).
So I just tried to create some walls, add some objects and export all to OBJ format.
After importing it in Twinmotion, the walls and objects are on side ! 90° rotated ! Strange to see a house like this...
Does anybody had same bug ?
Is it an bug when export OBJ ?
Thanks,
Vincent
